It should have come with directions and 3 packets of PH calibrating solution. Mine did.

How can I calibrate if i dont have the powders?

you can NOT cal. if you do not have the powders. my three powder bags come with the package. you can order the calibration powders from amazon. I strongly recommend using THREE point cal. so in this way, I got good results.

will this work for checking ph level when making cheese?

I don’t make cheese but I do make hot sauce. In my experience it works well but make sure to rinse the probes off when you are done.

pH meter calibration method: 1. Pour water in the cup (preferably distilled water or pure water) (Don’t use tap water or mineral water, otherwise it will affect the data) 2. Add 6.86 of correction powder (the green one), stir evenly to fully dissolve. 3. Remove the cover of the ph meter, turn it on (press ON/OFF button), immerse the probe in the prepared calibration solution, first look at the reading, if the data is consistent with 6.86 or the difference is relatively small, no calibration is required. If the value deviates from 6.86, and the value is relatively large, press and press the CAL button for 5 seconds, and the automatic calibration is in progress. It is expected that the value read after 5 seconds is stable, and the calibration is completed. Finally, clean the electrode with pure water, drying the water on the pen tip in time, and cover the pen cover. 4. Use the same method for 4.00/9.18 calibration powder.

No pude hacer uso del producto debido a que no contaba con el sensor en estado conveniente, recomendación revisar bien así como los componentes que deben venir. Llegó posterior a la fecha que se me había informado, y cuando por fin llegó no cumplia con lo mencionado (debían haber mínimo 3 sobres de soluciones buffer y no venían), desafortunadamente el sensor venía roto, por lo cuál, solicite mi reembolso..

So far I've had no issues with my meter. I bought this to test the ph of my feeding solution for my plants and I have to say I love it. Before I was only using strips and drops and this is a game changer and definitely a must have when growing plants that only uptake nutrients in a very specific ph range. This is a much better quality and priced meter (in my opinion) than the ones I've seen in any hardware or even local hydro stores. It comes with 3 packets of ph calibration solutions (6.86, 4.00, 9.18) and my meter tested on point every time during calibration. Just make sure to use clean water and peper towels to clean it off and take care of it everytime after you use it or before you put it away or you will ruin or compromise the electrodes.
